A single engineered corrosion protection ecosystem backed by Zerust Integrity Solutions.

A complimentary, structured corrosion program included for Zerust customers.

Supported by NTIC test labs on four continents, providing verified performance rather than claims on a data sheet.

Cased crossings under roads and rail can develop metallic shorts that divert cathodic protection current and accelerate corrosion. ZIS provides engineered VCI gel, powder and slurry systems that are installed through existing vent pipes in accordance with NACE SP0200-2014, requiring no excavation and allowing treatment of the annulus without interrupting operations.

ZIS provides engineered inhibitor delivery systems for pipeline staging, hydrotest layup and pre-commissioning preservation. These systems protect internal surfaces during idle periods without relying on dry air or nitrogen purging in suitable applications, reducing cost and simplifying operations.

Vapor corrosion inhibitors (VCI) distribute throughout an enclosed volume, form a microscopic protective layer on metal surfaces and block moisture and contaminants from reacting with the metal. When the space is opened, the inhibitor naturally dissipates, no wipe-down, no removal step, no residue to manage before the asset goes back into service.

The protection applies itself, and it removes itself.

VCI vs SCI: two modes of protection

VCI provides non-contact protection, forming its layer inside enclosed volumes without needing to touch the metal. SCI provides contact protection, delivering inhibitor directly to the surface where continuous contact is required. Together they extend protection into voids, crevices and hard-to-access surfaces where physical access is limited.

Blocks dirt, abrasion and corrosive gases such as SO2 and H2S from reaching the metal.

Interrupts the electrochemical reaction between anodic and cathodic points on the metal surface.

VCI films, papers, foams, wraps, liners and desiccants for controlling environmental exposure and stored component protection.

Emitters, diffusers, capsules and pouches for voids, enclosures and sealed volumes.

Powders, liquids and hydrostatic additives for pipelines, tanks, hydrotests, wet layup and idle equipment.

Industrial cleaners, degreasers, rust removers and converters for pre-preservation cleaning and recovery.

8-mil (200µm), high-strength VCI shrink film with UV stabilisers for long-term outdoor asset preservation; excellent shrink, handling and drape; safe for electronics; contains ≥10% recycled content and is fully recyclable.

Portable VCI capsules for non-contact corrosion protection inside control panels, electrical cabinets and other sealed enclosures. Diffuse invisible, odorless, non-toxic VCI molecules that protect multiple metal types for 1 to 2 years (model-dependent), even during operation. Quick adhesive installation; VCI dissipates on removal, allowing immediate painting, welding or processing.

UV-stable, hydrophobic, VCI-enabled wrap that protects via contact and non-contact inhibition (crevice, galvanic, atmospheric). Rated to ASTM B117: 4,000 hrs for harsh offshore environments; water-resistant, abrasion-resistant, non-flammable and rainproof. Conforms to any geometry, self-levels, requires minimal surface prep and remains effective even on severely corroded surfaces. Ideal for fasteners, flanges, valves, casings, structural nodes, corners and joints.

High-performance outdoor corrosion-preventive coating that forms a durable, transparent, dry-to-touch amber film for long-term protection of steel assets. Provides up to 2 years outdoor protection (longer indoors), allows visual inspection, applies by spray, brush, roller or dip, and removes easily by solvent or high-pressure wash. UV and weather-resistant, suitable across fabrication, transit, storage, layup and maintenance. Ideal for compressors, pumps, turbines, generators, pipe spools, skids, structural steel, spare parts and staged components.

Mildly alkaline, water-based cleaner with flash-rust inhibition for removing and deactivating chlorides, oils and corrosion-promoting contaminants. Compatible with hard water across a wide operating range; suitable for ferrous alloys and stainless steel (test on non-ferrous). Can be rinsed off or left as a dry-in-place cleaner for short-term flash-rust protection.

Grease-based rust preventative and lubricant that sprays on as an oily, cling-on coating for indoor protection up to 2 years and sheltered-outdoor protection up to 1 year. Lubricates moving parts, provides multimetal and yellow-metal compatibility, and is safe for painted and plastic surfaces. Easy to apply and remove, making it suitable for long-term storage and exposed equipment.

Sustainability

ZeCycle, run with recycling partner RecycleMax, takes used Zerust VCI packaging out of landfill and back into new product. Used film is sorted on-site, baled, collected, washed and reground into recycled pellets, then remanufactured into ICT 510-PCR30 VCI film.

Natur-VCI, a fully biodegradable and compostable VCI film, is also available for customers who need it.

Problem: A ferrous vertical sump pump was exposed to flash corrosion during hydrotesting and wet lay-up.

Fix: ZerioGuard 5 soluble inhibitor powder dissolved into the test water, creating an alkaline environment that neutralised acidic species.

Result: Flash corrosion prevented through testing and short-term lay-up, with no additional post-hydrotest treatment.

Problem: Flange-interface corrosion was driving seized bolting, leaks and costly maintenance.

Fix: ZIF Tape, a self-fusing silicone tape with embedded inhibitors, cold-applied and spiral-wound to deliver inhibitor straight to the metal surface.

Result: Flange integrity maintained without downtime, with assets kept protected and inspectable.
